A SpaceX Falcon 9 rocket blasted off from California on Saturday and placed a constellation of satellites in orbit, marking the company's first launch since a fireball engulfed a similar rocket on a Florida launch pad more than four months ago, the AP reports. The two-stage rocket lifted off from Vandenberg Air Force Base at 9:54am carrying a payload for Iridium Communications Inc., which is replacing its entire global network with 70 next-generation satellites. The satellites were deployed about an hour after launch. About nine minutes after the rocket blasted off, to cheers from the control room, its jettisoned first stage landed upright on a so-called droneship in the Pacific Ocean south of Vandenberg—part of Spacex's effort to make boosters reusable. The company has succeeded six times previously with landings on a barge or ashore.

A camera aboard the first stage gave viewers a you-are-there experience as it returned to Earth, flared landing rockets and made a perfect upright touchdown on the floating pad. The return to flight is an important step for SpaceX, billionaire Elon Musk's California-based company that has about 70 launches in line, worth more than $10 billion. In addition to commercial launches, SpaceX ferries supplies to the International Space Station and is developing a Falcon capable of carrying astronauts to the station. SpaceX officials say they identified all possible causes of the Sept. 1 accident during prelaunch testing at Cape Canaveral Air Force Station, Florida, and took corrective action. The accident destroyed the rocket and its payload—a satellite that Facebook wanted to use to spread internet access in Africa—and grounded the Falcon 9 program as an investigation took place.

thank god there are driven visionary men like Musk to keep dreaming big. Very impressive to see the rocket go up then land.

This is good news. The sooner we are no longer dependent on Russia for rides and deliveries to the space station, the better I'll like it. IMHO, we should never have discontinued the space shuttle program before we had a reliable way of maintaining our presence in space.
